Trick to this build is to use tele to avoid swarms and heard them into a line or narrow passage and unleash a folly of strafe. With this build I had 478% Ias and 372% Fcr so speed was never an issue. Eagle eye is a viable option for a boss killer as the massive IAS will still hold up well with the speed negativity of EE. For dueling use multi shot and tele to get a arc of arrows coming from several directions for sorcs and for other classes without tele just port around and pluck a few arrows out

Only other thing to watch out for is mobs in throne room as in hell the leech is greatly reduced. With Moonlight bow equipped I had both leeches at around 80% so aside from no leech able monsters I had no troubles.
